Its basin covers 21,900 km², about the size of SV. 1.1 million people live in it. Highest water: from September to October; lowest: from January to April. No large dam holds it back: it is one of the world's free-flowing rivers.

Saint Paul River, month by month
Highest water: from September to October
Lowest water: from January to April. Best months to visit: from December to January.
From about 140 m³/s in the lowest month to 2,200 m³/s in the highest. An estimate: the monthly flow is modelled from the lowest and highest months of WaterGAP (RiverATLAS, 1971–2000) and the rain and snow along the river (WorldClim). Dams change the real rhythm. The chip is the average air temperature; below it, the month's rain.
